2015-10-01rfkill: rework and make it listen on /dev/rfkillLennart Poettering
With this rework we introduce systemd-rfkill.service as singleton that is activated via systemd-rfkill.socket that listens on /dev/rfkill. That way, we get notified each time a new rfkill device shows up or changes state, in which case we restore and save its current setting to disk. This is nicer than the previous logic, as this means we save/restore state even of rfkill devices that are around only intermittently, and save/restore the state even if the system is shutdown abruptly instead of cleanly. This implements what I suggested in #1019 and obsoletes it.
2015-07-06fileio: consolidate write_string_file*()Daniel Mack
Merge write_string_file(), write_string_file_no_create() and write_string_file_atomic() into write_string_file() and provide a flags mask that allows combinations of atomic writing, newline appending and automatic file creation. Change all users accordingly.
2014-12-03rfkill: rework how we generate file names from rfkill devicesLennart Poettering
Generate the file name from ID_PATH plus the rfkill type (wlan, bluetooth, ...) and ignore the rfkill device name, since it apparently is not a stable identifier. Also, ensure that devices disappearing don't result in broken services, simply exit cleanly.
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2013-12-06rfkill: Avoid error when state restore is disabledBastien Nocera
When the state restore is disabled, we would print: "Unknown verb: load" instead of simply skipping loading the state.
2013-11-06util: unify reading of /proc/cmdlineLennart Poettering
Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.
2013-10-19trivial: rfkill - don't include util.h twiceTom Gundersen
2013-10-19trivial: rfkill: It's util.h, not utils.hColin Walters
How about we actually run make locally before pushing, eh?
2013-10-19kerne-command-line: introduce option 'systemd.restore_state'Tom Gundersen
When set to 0 this will stop tools like the backlight and rfkill tools to restore state from previous boot. This is useful in case the stored state is bogus to the extent that it is preventing you from resetting it (e.g., the backlight settings cause the screen to be off on boot on a system where the backlight can not be adjusted directly from the keyboard).
2013-10-14backlight: include ID_PATH in file names for backlight settingsLennart Poettering
Much like for rfkill devices we should provide some stability regarding enumeration order, hence include the stable bits of the device path in the file name we store settings under.
2013-10-14rfkill: use ID_PATH as identifier for rfkill state filesLennart Poettering
Let's include the stable device path for the rfkill devices in the name of the file we store the rfkill state in, so that we have some stability regarding enumeration order.
2013-10-14rfkill: add new rfkill tool to save/restore rfkill state across rebootsLennart Poettering
This works analogous to the existing backlight and random seed services
